Hi zhenwei pi,

util-linux supports two new commands irqtop/lsirq since v2.36.
The related release note: https://lwn.net/Articles/826866/
The irqtop(from util-linux) command has better user experience:
- aggregate interrupt information seems clear on a morden server(128
CPUs or more).
- sort by several rules, include IRQ, TOTAL, DELTA and NAME.
- specify cpus in list format to monitor.
- specify output columns to print.
The lsirq command supports:
- specify output columns to print.
- sort result.
- raw/json/KV format to show.
thanks for the reminder. For irqtop, I had some discussion with the
maintainer of the current irqtop package (CC'ed now). I cannot
remember if we came to a conclusion though. Axel, maybe you can
remind me...
lsirq - right, will probably put it into util-linux-extra soon. Or
do you think it should be part of the util-linux Essential API?

Hi, Chris
lsirq reads /proc/interrupts and shows the basic IRQ information of an
OS, it's a common and standard function. From the point of my view, to
be part of util-linux seems better. Please correct me if I misunderstand
the difference between util-linux and util-linux-extra package. Thanks!
